The items cover five domains, which are work, social, energy and vitality, feeling and concerns, and symptoms. Satisfactory cross cultural equivalence of the Dutch WOMAC in patients with hip osteoarthritis waiting for arthroplasty. Specifically, all pain items loaded on one factor and all function items on another.
Validity and factor structure of the AUSCAN Osteoarthritis Hand Index in a community-based sample
Partial correlations Spearman represent the association of one subscale with the strength or pain item while controlling for the other subscale. Is there a difference in the perception of symptoms between African Americans and whites with osteoarthritis. Radiological assessment of osteoarthrosis. Results for the total sample are not shown but were similar to the factor loadings for the Caucasian group shown in Table V.
The eigenvalue for a given factor measures the variance in all variables that is accounted for by that factor. There may be individual differences in the types and difficulty of tasks that individuals think about when responding to pain items i. To examine construct validity of the subscales, we assessed correlations of all three AUSCAN subscales with hand strength grip and pinch strength for both right and left hands and the self-reported right and left hand pain four-point scale.
This study examines whether the AUSCAN’s intended factor structure is valid in a larger, more diverse and generalizable sample. Construct validity was also supported, as grip and pinch strength were more strongly correlated with the AUSCAN function subscale than with the pain and stiffness subscales. Open in a separate window. It assesses the three dimensions of pain, disability and joint stiffness for patients with osteoarthritis of the hip or knee.
Conclusions Results support the validity of the AUSCAN in a general sample of adults, as well as across demographic and clinical subgroups, although the subscale structures differed slightly by race. Author information Copyright and License information Disclaimer.
Australian/Canadian Osteoarthritis Hand Index (AUSCAN)
There was a minor deviation from this pattern for the subgroup of patients who reported that they did not have current hand pain on the single-item measure.
National Center for Biotechnology InformationU. Results of this analysis were similar for men, women, all quesstionnaire groups, Caucasians, participants with questoonnaire without radiographic hand OA using both definitionsand participants with and without self-reported hand pain. Results of the exploratory factor analysis with the number of factors not specified are shown in Table IV for the full sample.
The views expressed in this manuscript are those of the authors and do not necessarily represent the views of the Department of Veterans Affairs. Denmark Finland France Germany Hungry. KL grading is a standard and the most common method for assessing radiographic hand OA. To further assess the construct validity of the pain and function subscales, which were of particular interest, we examined the partial correlations of these subscales to hand strength and the self-reported hand pain items.
Support Center Support Center. Prior studies have involved small clinical samples 1 — 3 and family-based samples 45. With respect to gender, associations of AUSCAN subscales with pinch and grip strength were slightly weaker for men than women, but these were all statistically significant for both groups and followed patterns similar to those shown in Table II.
However, we did not observe a clear factor pattern corresponding to activity type in this analysis. Studies have shown this measure has acceptable reliability, construct validity, and responsiveness 1 — 5.
Furthermore, internal consistency was acceptable for all subgroups we examined, including individuals without self-reported hand pain and individuals without radiographic hand OA. Because the AUSCAN is a relatively new scale, it is important to examine its utility and measurement properties in a variety of populations and settings to evaluate the generalizability of this scale.
Factor analysis showed that for the full sample and most subgroups, all pain items loaded on one factor standardized regression coefficients 0. A cross-sectional study of the association between Heberden’s nodes, radiographic osteoarthritis of the hands, grip strength, disability, and pain.
AUSCAN Osteoarthritis Index – AUSCAN – Hand Osteoarthritis
This may indicate some weakness in the construct validity and specificity of the AUSCAN pain subscale among these subgroups. For the total sample, all pain subscale items clearly loaded on one factor and all function items on another.
This is particularly important because the AUSCAN scale developers have endorsed the use of the subscales individually 4. Several of these have been made available for distribution through us by their developers.
Validation of an algofunctional index for osteoarthritis of the hand.
